Hand Computation of this, same with the result of the software excel and jamovi:
A psychologist would like to research if the Hope scale(Synder, et al., 1991) scores differ between those living in City A and City B. The 12-item scale consisted of two subscales: a 6-item agency subscale and a 6-item pathways subscales. Scores on the 12 items were averaged, with higher scores indicating higher levels of hope. The following scores were obtained.
Use Student’s t-test for Independent Groups, alpha at .05 2 tail
City A - 43 38 36 38 52 60 58 66 55 63
City B - 62 34 35 52 58 72 57 55 80 67
